CTsFastSwapPreviewProvider Class Reference

class CTsFastSwapPreviewProvider : public CBase

Preview provider API class. Applications (window groups) must be registered before screenshots can be received. Also, closed apps should be unregistered to save resources. TakePreview() can be called to take a screenshot right away. A client needing notifications has to create an instance so that screenshots can be delivered to it via MTsFastSwapPreviewObserver.
